Are you feeling difficulty in calculating the elapsed time? Don’t worry we are here to help you to overcome the difficulties in calculating the time. Before that, you have to know what the elapsed time is. Elapsed time is the calculation of time that passes from starting off a program till its end.

It is very important to know how to calculate the elapsed time to know time. There are different techniques to calculate the elapsed time. One method is the time interval between the start of an event to the end of the event. Another method is the number line on which we break up the time intervals. We suggest the students of 5th grade go through the article and solve the given problems. Learn the concept with suitable examples and score good marks in the exams.

## What is Elapsed Time in Math?

Elapsed time is the amount of time duration from the start of the event to the finish of the event. In simple words, the elapsed time is the time that goes from one time to another time.

### How to Calculate Elapsed time?

- For solving the elapsed time first we would find the starting time and ending time.
- Second, counts the hours and minutes between the starting point to noontime and from noontime to ending time.
- The third is finding out the elapsed time by adding durations.

### Elapsed Time Examples

**Example 1.**

Find the elapsed time from 7.00 am to 8.00 pm?

**Solution:**

Given that,

Starting time = 7.00 am

Finishing time = 8.00 pm

The difference between 7.00 am to 12 noon = 5 hours

The difference between 12 noon to 8.00 pm = 8 hours

Duration time = 5 hours + 8 hours = 13 hours.

Duration time is 8 hours

**Example 2.**

Find the elapsed time from 7 hours 30 minutes to 3 hours 20 minutes?

**Solution:**

7 hours 30 minutes – 3 hours 20 minutes

7 hours – 3 hours = 4 hours

30 minutes – 20 minutes = 10 minutes

The elapsed time = 4 hours + 10 minutes = 4 hours 10 minutes

**Example 3.**

What time would it be 3 hours 30 minutes after 8 am?

**Solution:**

Given that,

Present time = 3 hours 30 minutes

After time = 8 am = 8 hours

Therefore 3 hours 30 minutes + 8 hours

Time would be 11 hours 30 minutes.

**Example 4.**

The starting time is 11.25 am and the finishing time is 3.40 pm. What is the duration of the time?

**Solution:**

Given that,

Starting time = 11.25 am

Finishing time = 3.40 pm

The difference between 11.25 am to 12 noon = 35 minutes

The difference between 12 noon to 3.40 pm = 3 hours 40 minutes.

Duration time = 35 minutes + 3 hours 40 minutes

35 minutes + 40 minutes = 1 hour 15 minutes

3 hours + 1 hour 15 minutes = 4 hours 15 minutes

Therefore, the Duration time is 4 hours 15 minutes.

**Example 5.**

If the movie starts at 4 pm and ends at 8 pm. How long is the movie?

**Solution:**

Given that,

Starting time of the movie = 4 pm

Finishing time of the movie = 8 pm

Duration of the movie time = 4 pm – 8 pm = 4

Thus, the duration of the movie is 4 hours.

### FAQs on Elapsed Time

**1. What is elapsed time?**

An elapsed time is the amount of time taken to travel or to start from one place to another place.

**2. How do you calculate elapsed time?**

1. First count in minutes from earlier time to the nearest hour.

2. Count on hours to the hour nearest to the later time.

3. Then count in minutes to reach the later time.

**3. How do you subtract elapsed time?**

In order to subtract the time, subtract the minutes and then subtract the hours.
